Saia Fainga'a has been called into Australia's squad for the Rugby Championship after another injury setback.

The Wallabies have already seen experienced hookers Stephen Moore and Tatafu Polota-Nau ruled out, but now Tolu Latu has joined them on the sidelines.

Latu broke an arm in a Sydney club game on the weekend, opening the door for Fainga'a to return.

The Reds hooker, who has been capped 29 times, joins Nathan Charles and team-mate James Hanson in competing for the No 2 jersey.

Australia's preparations for Saturday's opening game against New Zealand in Sydney have been disrupted by a nunmber injury issues, with Scott Sio, Henry Speight, Joe Tomane and Laurie Weeks among those to pick up knocks.
